Description

Applications installing application-specific recovery methods need to be called before Berkeley DB performs recovery so they may add their recovery methods to Berkeley DB's.

The DbEnv.set_recovery_init method supports this functionality. The db_recovery_init_fcn method must be declared with one argument, a reference to the enclosing Berkeley DB environment. This method will be called after the DbEnv.open has been called, but before recovery is started.

If the db_recovery_init_fcn method returns a non-zero value, no recovery will be performed, and DbEnv.open will return the same value to its caller.

The DbEnv.set_recovery_init interface may be used only to configure Berkeley DB before the DbEnv.open interface is called.

The DbEnv.set_recovery_init method throws an exception that encapsulates a non-zero error value on failure.

Errors

The DbEnv.set_recovery_init method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL

An invalid flag value or parameter was specified.

Called after DbEnv.open was called.

The DbEnv.set_recovery_init method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv.set_recovery_init method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
